This Old House plumbing and heating expert Richard Trethewey explains how to capture the heat buried deep in the ground. SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse Richard took a homeowner to visit a house that had a ground-source or "geo-thermal" heating and air conditioning system. During the heating season, this type of HVAC system uses a heat-pump to move heat from the ground into the house. In cooling season, the heat-pump runs in reverse, moving heat from the house into the ground. The geo-thermal heat pump that the homeowner had installed was manufactured by ClimateMaster [https://www.climatemaster.com/].
